Dielectric resonators: application for scientific research


Progress of the resonant methods and devices on the basis of Whispering Gallery Modes (WGM) open disk dielectric resonators (DDR) for technological and scientific research: parameters of dielectric and semiconductor materials; fundamental investigations; modeling of the processes in optical quantum devices.

Innovative Aspect and Main Advantages

  • dielectrometry of materials with small and super small losses at wide frequency and temperature ranges;
  • study of fundamental properties of superfluid helium at extra-high frequencies (EHF);
  • modeling of the microresonators and transmission lines at optical wavelengths;
  • design of new controlled elements at terahertz (THz) band.

Areas of Application

  • technology of new dielectric and semiconductor materials;
  • fundamental research in condensed matter physics;
  • modeling of optical devices for quantum computers.
